contacting the brewery is a great idea. or just give it a try. it won't cost must. when you are ready to drink the beer boil up some 1.020-1.030 un-hopped wort. you won't need much, just 50 ml or so. sanitize the bottle cap and neck, and the bottle opener and pop it open. wipe the lip of the bottle with high proof alcohol (140+) and pour gently leaving the last couple ounces. add 50 ml of wort and cover with an air lock. after a week or so add another 100ml or add the dregs to 500 ml if they seem active. 500 ml can be pitched into a 2 gallon batch easy.
